Bewkar,
You have my utmost respect, from a fellow Templar and aspiring chef. If you've put the time and grind into making Prov 50, I say get whatever you desire. I'm only a 22 provisioner and I can't even bring myself to grind the next level and a half to be able to make tier 3 drinks.
Regarding your buffs / debuffs:
You may want to look at your Individual WIS buff (Protectorate I think), or your group health / power buffs like Symbol of Ryltan or Protective Faith. No idea what the difference between App IV and Ad III is, but I use these all the time.
I also use Disgrace to pull solos or fight in groups. At 30, one of the specialized spells is a upgrade to that, but I took the group elemental cure.
